摘要： The invention relates to a boring tool that includes a boring bar having a center axis which at a top portion of the bar is arranged to be connected to a machine tool, and which at a bottom portion of the bar along the center axis is slit into two legs. The two legs can be movable towards or away from each other, such as by means of an adjusting screw, for exact adjustment of the position of the cutting tool with relation to the center axis. The tool is arranged in such a way that a joint through bar is detachably attached to the bottom of each of the legs of the boring bar. This joint through bar extends essentially perpendicular to the slit and center axis, and enables a cutting tool to be provided at the end of the bar. Hereby an especially simple tool is obtained which can be adjusted extremely precisely for fine machining of holes.
